Both incidents took place on Wednesday 15 January. A man entered a shop in High Street, Coltishall, at approximately 12.50pm and a business premises in Millers Walk in Fakenham at approximately 3.15pm.

At both locations the man bought small items before asking to change several notes into different denominations.

He did this a few times to confuse the cashier who then ended up handing over more money than they should have during the transaction.

Officers are keen to identify the man pictured in the CCTV image who may be able to assist with enquiries.

Anyone with information should contact Sgt Toby Gosden at North Walsham Police Station on 101 or call Crimestoppers anonymously on 0800 555 111.
